摘要:
An electric refrigerator is provided with a casing (51) formed of a heat-insulating layer and defining an opening; a heat-insulating door (52) for openably closing the opening of the casing (51); a thermal conductor (53) arranged in the casing (51) and provided with a heat-conducting surface located opposite an interior space in the casing (51); a Peltier device (55) thermally connected with the thermal conductor (53); and a device power supply (61) for feeding electric power to the Peltier device (55). The electric refrigerator is also provided with a control unit (63) for controlling the device power supply (61) so that, after the heat-insulating door (52) is closed subsequent to opening thereof, the device power supply (61) supplies the Peltier device (55) with electric power controlled in a range of from 1.3 to 2 times as much rated electric power required to maintain a preset interior temperature of the casing (51).

摘要:
One of a heat-absorbing-side thermal conductor (1) and a heat-dissipating-side thermal conductor(3) is substantially in a form of a single piece. Plural groups of thermoelectric elements (4a,4b) are arranged relative to the single-piece thermal conductor (1). Corresponding to the plural groups of thermoelectric elements (4a,4b), the other one (3) of the heat-absorbing-side thermal conductor and the heat-dissipating-side thermal conductor is arranged in a form divided into a like number of pieces (3a,3b).
